Description

After upgrading to 4.1.0 final I cannot start any of my Windows VMs - either existing or newly created. VirtualBox just crashes with Guru Meditation -2 (VERR_INVALID_PARAMETER) in log. Two non-Windows machines (Android and openSUSE 11.1) boot without crash, but it's hard to tell whether it's a general rule or just a coincidence.

Hello,
I have the same issue but with version 4.1.2.R73507. I(ve tried a vhd that work well on VPC and another that I can't try before but all with the same result. I've try to load Windows server 2003 (32 bits) and windows server 2008 (64bits). My host run under Windows 7 home edition.
